My MP3 players are several years old, and have batteries that cannot be replaced. I have A/C speaker docks that are designed specifically for these MP3 players. The speaker docks provide power to the players - (that is, they charge the MP3 battery when docked). Anticipating that the MP3 batteries will eventually die, will I still be able to use these players when docked?
Light bulbs you shouldn't buy
There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
